Here are the latest WAV Trigger firmware and related utility executables. Project source files for some of the utilities, along with builds for OS X and Linux, can be found in the respective github repositories.

Release notes: Preliminary release for testing. MIDI Program Change messages will now change the MIDI bank number. MIDI Real-time Stop (0xFC) immediately stops all voices (all notes off). Fixed issue with looping tracks not responding to stop commands if the end of track was reached before the fade out finished. Mostly affected very short tracks with the loop flag set.

Release notes: Latest Release Version Optimized mix engine and memory to get additional two voices for a grand total of 14 stereo voices. Implemented low power “sleep” mode option. See this blog post for details.

Release notes: Preliminary release for testing. Added a voice-stealing algorithm so that the most recent trigger or MIDI Note-On always gets a voice, stealing from the oldest one playing. This is how most MIDI samplers work. Improved MIDI attacks. Fixed a potential crash when lots of voices are playing. Fixed bug with track numbers greater than 255.

Release notes: Triggers that have both “Polyphonic” and “Re-Trigger” disabled will now not re-trigger if any tracks are playing, regardless of how those tracks were triggered. Triggers with “Polyphonic” enabled and “Re-Trigger” disabled will not re-trigger only if tracks from that trigger are playing.

Release notes: Adds support for controlling individual track volumes as well as enabling/disabling the audio amplifier. These functions require firmware version 0.57 or above.

This is a sample remote control program, meant to show the basics of controlling the WAV Trigger from a host computer. It’s not something I provide support for. If it doesn’t do what you need, please feel free to make your own improvements and enhancements. See the link to the source code below.
